There have been recent reports of outbreaks of illnesses from the consumption of various synthetic cannabinoid products. Symptoms reported in these last outbreaks include violent behavior, seizures, and other cardiac issues. Products are just now being analyzed and the specific cannabinoids identified. While the cannabinoids are worrisome on their own, now comes this report from Manatee county, Florida.The
sheriff's office in Manatee county has issued a warning that there may
be synthetic cannabinoid products out there that contain the pesticide
acephate. Two kilograms of a substance allegedly meant for use in "spice"
products was acquired by authorities. The substance was later identified as
acephate.

Acephate
is an organophosphate pesticide used to control insect pests such as aphids,
caterpillars, and sawflies. Its IUPAC nomenclature is O,S-Dimethyl N-acetylphosphoramidothioate. Chemical formula is
C4H10NO3PS.

According to the World Health Organization (WHO) toxicity class system, acephate is a class III (Slightly Hazardous) substance. Upon
heating, acephate decomposes to form oxides of nitrogen, phosphorus, and
sulfur.

In insects, acephate
is biotransformed into methamidophos, another active
organophosphate compound. Methamidophos is also available as the pesticide
Monitor. Its IUPAC nomenclature is O,S-Dimethyl
phosphoramidothioate. Chemical formula is C2H8NO2PS. According to the WHO toxicity class system, methamidophos is classified as a class IB (Highly Hazardous) substance.

In humans, tranformation to methamidophos is relatively minor and the major metabolite is O-desmethylacephate. What do organophosphate compounds such as these do while in the human body?

They inhibit the enzyme acetylcholinesterase (AChE) via phosphorylation, which ultimately results in an accumulation of the neurotransmitter
acetylcholine (ACh) in the body. An excess of ACh can lead to
overstimulation of the nicotinic acetylcholine receptors (nAChRs) and muscarinic
acetylcholine receptors (mAChRs) which are part of the parasympathetic nervous
system (PSNS).

Salivation, Lacrimation, Urination, Defecation, Gastrointestinal
motility, Emesis, MiosisNature's Poisons recently wrote about nicotinic acetylcholine receptors and resulting effects of activation of said receptors. I previously wrote a short bit on muscarinic acetylcholine receptors and results effects of receptor activation.For quite some time, I've wondered if something like this would happen. If this is to be believed as legit, then I'm not sure the logic. Other than to harm, what is the reasoning behind using an organophosphate pesticide in a cannabinoid smoking blend? I've seen some strange things contained in blends in the past, but I'm truly bewildered by this one. I don't usually give advice on these topics, but I will do so now.Stay away from synthetic cannabinoid blends. Do not use them.If more information is released about this, I'll update.Stay safe.
